After watching urlclassifier3.sqlite grow to 50-100 MB in FF3, I turned the options off. Don’t fall for these tricks anyway.
I’ve been hanging onto v.2 as some add-ons haven’t been updated.
On the other hand, I hope v.3 handles videos and audio better. Many news videos posted at TV stations just plain don’t load with Firefox and I go to IE immediately to watch them instead of waiting forever(and still not seeing them). Same with audio streaming of some of my favorite talk radio shows.
More than the file size, I have found the unexplained network activity disconcerting, in addition to disk accesses, both of which have dropped after disabling the attack site and phishing options. Addons such as noscript handle many of the attack types anyway.
Is this a feature in FF 3??
Is it easy to turn off??
